A hernia is a medical condition that occurs when an internal organ or tissue protrudes through a weak spot or opening in the surrounding muscle or connective tissue. This can happen in various parts of the body, but the most common types of hernias include inguinal (groin), umbilical (belly button), and hiatal hernias (stomach tissue pushing up through the diaphragm into the chest cavity).
Hernias can lead to discomfort, pain, and potential complications if left untreated, such as strangulation (where the blood supply to the protruding tissue is cut off). Treatment often involves lifestyle changes, supportive devices, or surgical repair, depending on the severity and type of hernia.
